摘要： A magnetoresistance effect type thin film magnetic head comprising an MR element with electrodes provided at a fore end and a rear end thereof in the direction to confront a magnetic recording medium, wherein the electrode at the fore end of such MR element is electrically connected to a shielding magnetic layer to thereby eliminate any electrical instability at the fore end of the MR element, hence averting the characteristic instability in a playback mode while minimizing the unsteady generation of noise. The thin film magnetic head further comprises a first conductor having a great capacity and disposed in the proximity of the MR element, and a second conductor having a capacity smaller than that of the first conductor and connected to the fore-end electrode of the MR element. Such first and second conductors are connected to respective ground potentials independently of each other, thereby averting breakdown of the magnetic head that may otherwise be caused by the static charge generated due to the rotation of the magnetic recording medium during the operation.

摘要： A magneto-resistance effect type thin film magnetic head which does not produce significant Barkhausen noises and has stabilized characteristics even where the track width is smaller than, for example, 10 .mu.m. The magnetic head comprises a base member, a lower layer thin film magnetic core and an upper layer thin film magnetic core layered on the base member in such a manner that a magnetic gap is formed between front ends thereof, the gap being open to an opposing face of the magnetic head which is in contact with or opposed to a magnetic record medium, and a magneto-resistance effect magnetic sensing section disposed in the magnetic gap between the lower and upper layer thin film magnetic cores. The front end of the lower layer thin film magnetic core which defines the magnetic gap has a width selected to be smaller than the width of the front end of the upper layer thin film magnetic core which defines the magnetic gap so as to define a track width of the magnetic gap.

摘要： A magnetic reluctance effect magnetic head in which a forward side electrode is stacked on at least the surface of a magnetic reluctance effect element facing a magnetic recording medium, and in which an upper magnetic pole is stacked on the forward side electrode for facing the magnetic reluctance effect element. A connecting length L1 between the magnetic reluctance effect element and the forward side electrode is shorter than a facing length L2 over which the upper magnetic pole and the magnetic reluctance effect element face each other via a magnetic gap G. The upper magnetic pole and the magnetic reluctance effect element have an area in which the upper magnetic pole and the magnetic reluctance effect element face each other over a distance g2 larger than a magnetic gap length g1 of the magnetic gap G. The upper magnetic pole may be formed to be progressively spaced apart from the magnetic reluctance effect element by being angled 30.degree. relative to the magnetic reluctance effect element, and the distance g2 may be progressively increased. With the magnetic reluctance effect magnetic head, the playback output may be improved and the magnetic head may be reduced in size and in the power consumption.
